Hybrid tea rose plant named `TWOAEBI`

ABSTRACT

A new rose cultivar of the Hybrid Tea class characterized by having a very double, very long lasting, non-fading, orange flower, with very consistent blooms. This plant has been designated as `TWOAEBI`. It is being marketed in the USA under the tradename of `Dream Orange`.

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing `Cherish` as the seed parent with the pollen parent an un-named seedling.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

(a) All other cultivars of which I am aware are: (1) Does well as both a garden and greenhouse rose. (2) Very long lasting. (3) Consistent free bloomer. (4) Yon-fading orange flower.

(b)

Seed parent.--Coral/pink, cluster flowered, Floribunda.

Pollen parent.--Red flowered, Floribunda.

Asexual reproduction of the new rose cultivar by budding, as performed at Wasco, Calif. shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart, e.g. "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.

Parentage:

Seed parent.--`Cherish`, U.S. Plant Pat. No. 4,331.

Pollen parent.--Seedling -- (Evening Star×Trumpeter).

Class: Hybrid Teas.

The following observations are made of specimens grown outdoors in Monterey County, Calif., in the month of August, 1998.
